Probes for CO and C02 meters

These probes are adjusted to digital air quality measurement devices in order to know the levels of CO or CO2 in the environment, preferably indoors.

CO2 is a residual gas of respiration, and can make the environment rarefied if a room or premises has been heavily frequented. CO or carbon monoxide is a very toxic gas, the result of bad combustion. Over-accumulation can be fatal.
